RAYMOND T. BELL, OF CHICAGO, ILLINOIS.

PENCIL.

Application filed January 9, 1922.

To all tri/wm t may conce/Mt.'

Be it known that I, RAYMOND T. BELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pencils, of which the ollowing is a specification.

This invention relates to improvements in pencils of the type in which the lead or crayon is adapted to be ted from the holder as the lead is consumed, and one off the objects o-il the invention is to improve and simplify the construction thereof and to produce a pencil which will be compact in construction, convenient for use and effective and e'icient in operation. p

A further object is to provide an improved pencil of this character embodying a cap which is operatively connected with thel lead propelling plunger and by means of the rotation ot which cap the plunger is aetuated, and improved means lor securingthe cap to the barrel or sheath of the pencil for rotation with respect thereto, and at the same time to provide improved means whereby the cap may be readily removed without danger of straining or injuring any of the parts.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement ot the several parts hereinafter more fully described and claimed and shownfin the accompanying drawing illustrating this invention, and in which- Figure 1 is a view in elevation.v

Figure 8is aside elevation of'Figure 7.

Referring more particularly to the draw; ing the numeral 15 designates the sheath or body oit the pencil', which may be of any desired size and vconliguration'and constructed of any suitable light material.

The sheath 15V is provided with a central bore 16 extending throughout the length thereof, and operatingin the bore is a lead Serial No. 527,979.

propelling plunger 17, which is operatively connected with a propelling member or screw 18.

Secured to one end of the sheath is a tip 19 and the other end of the sheath is reduced as at 20 to form a shoulder 21. Encompassing this reduced portion 2O is a sleeve 22, constructed of any suitable mat-erial, such as metal or the like. This sleeve lits snugly upon the `sheath and is provided with diametrically oppositeV laterally projecting lugs 23 intermediate the ends thereoit'. Encompassing the sleeve 22 is another sleeve 24, and this sleeve 24 is provided with diametrically opposite bayonet slots extending through the lower edge of the sleeve as at 25, the portion 26 of the slot being Aof any `desired length.

This sleeve 24 is adapted to be held in position about the sleeve 22 by positioning the open ends 25 of the bayonet slots so that. the lugs 23 on` the sleeve 22 will enter thereinto and after the sleeve 24 has been adjusted so that the lugs will stand adjacent the. portion 26 ofthe bayonet slot the lugs willenter that portion of the slotwhen the sleeve 24 is rotated with respect to the sleeve 22.

Th@J sleeve 24 is alsa/provided with a oircumferentially reduced portion 27 intermediate its ends and above the bayonet. slot the external diameters oit" the slee-ves 22 an 24 are less than the external diameter of the sheath 15 beyond the reduced portion.

A cap member 28 is adapted to extend over the sleeve 24 and also the adjacent extremity of the sheath 15. This cap member 28 .is provided with a sleeve portion 29, having a spring tongue 30 cut therefrom, and the tongue is vdeflected inwardly into the sleeve portion v29 as shownmore clearly in Figure 3. This spring tongue 30 is provided as a means for frictionally and yieldingly locking the cap 28 upon the end'of the sheath and co-operates with the sleeve 24 for locking the cap to the end of the sheath. When the cap 28 is placed'in position so that the tongue 30 enters the circumferential recess 27 of the sleeve 24, and which tongue is preferably' of a width slightly less than the width of the circumferential recess 27, the sleeve 24 and cap will be locked together and the sleeve 24 is locked with the sleeve .22 by means o'frthe lugs 23 and bayonet slots in the sleeve 24.

The operating screw 18'l'or the plunger 17 is connected with the cap 28 as at 31 for rotated'the screw 18 will be actuated and this will cause the plunger 17 to move forwardly or biaclrwardly in directions lengthwise of the sheath of the pencil in accordance with the direction ot' rotation ofthe cap.

yVhen the cap 28 is'rotated the frictional contact between the spring tongue 3() and the'bottom of the annular recess 27 inthe sleeve 24 will cause the latter to rotate with theycap until the lugs 23 on the sleeve 22 engage one or the other of the ends of the horizontal portion of the bayonet slot according to thedirection of rotation of the cap and by exerting a pressure upon the cap so as to hold thesame against the end of the sheath the sleeve 24 will, when the lugs 23 engage the end ofthe slot be arrested in its rotationand the cap 28 may then be rotated with respect to the sleeve 24. lVhen it is desired to remove the cap it is rotated so that the lugs 23 will stand adjacent the portion 25 of the bayonet slot in the sleeve 24C, after which the cap may be readily removed and with it the slee-ve 24 by moving the same in a` direction longitudinal of the .shaft and away from the sheath. e f

. The capi may be readily applied by r versing this operation.

With this improvedA construction it will bev manifest that the cap may be readily app-lied orl removed without in any manner injuring or damaging any of the parts of the mechanism.

Obviously and if desired additional tongues'SO may be employed.

While the preferred form of the invention vhas been herein sho-wn and described it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of 'the claims, without departing from the Spirit of thisinvention. f
